What can be done about printing the receipt without it using up an entire sheet of paper every time?
If you are using a regular printer to print them, then it must print an entire sheet since that is how regular printers work. If you want to save paper, they you must purchase a receipt printer. Before buying a receipt printer, ensure that the printer is compatible your Windows version, i.e. Windows 98. After installing the printer, select the receipt printer from the file menu area. Now, whenever you print a receipt, only the paper needed to print the receipt will be used.
